摘要： The invention relates to compositions and methods that are useful in etching a metal surface. In particular, the invention relates to novel acid compositions and methods of using such compositions in etching a metal surface, preferably an aluminum surface prior to anodizing to dissolve impurities, imperfections, scale, and oxide. The compositions are effective in maintaining their etching capacity and in removing smut produced by the etching of a surface as well as in general cleaning.

摘要： A method of anodic treatment for a metal workpiece combined with a non-metallic material includes steps as follows. A pretreatment process is applied to the metal workpiece. The metal workpiece is anodic oxidized, and washed with water. Then, the metal workpiece is put in a vacuum environment to evaporate a residual chemical agent between a metal part and a plastic part of the metal workpiece. The metal workpiece is washed with water. An activating treatment is applied to the metal workpiece. The metal workpiece is dyed, and is sealed.

摘要： This invention relates to a composition for the brightening and/or passivating of stainless steel after pickling. The invention is based on the discovery that the presence of organic compounds containing multiple hydroxyl groups with at least 3, but not more than 8 carbon atoms as a further ingredient of passivating and brightening solution significantly increases the desmutting performance of pickled stainless steel surfaces. The compositions of the invention are especially useful for the passivating and brightening of stainless steel grades being alloyed with sulfur. The invention thus further encompasses a passivating and brightening process for pickled stainless steel surfaces wherein the stainless steel is alloyed with at least 0.10 at.-% of sulfur.

摘要： This invention teaches the development of a chemical reagent useful as an aluminum brightening bath. The reagent's composition is primarily wet-process phosphoric acid to which has been added small quantities of nitric acid, copper, and optionally traces of several other substances. The reagent does not require expensive removal of the natural impurities found in wet-process phosphoric acid.

摘要： An improved process for preparing a polishing solution for use in the chemical-mechanical polishing of silicon comprising copper nitrate, ammonium fluoride, nitric acid and ammonium nitrate. The latter two components are added to the copper nitrate, the system mixed well and then the ammonium fluoride added. The process eliminates the need for settling, decantation or filtration during solution preparation and permits substantially lowered amounts of copper nitrate to be used for silicon polishing. The silicon polishing solution is also described.
